Hi, we have strange problem. We use nop 4.40.04.
Today i receive information about few our categories where we receive 404 error. When i start investigate it, we see in admin panel url of this category is "empty".
In database it's change to "notactive"
For now i don't know why it's happen, and how to reproduce it. We sometimes have something similar when we add new products (we need clear cache etc. and then it's works).
Maybe someone from you heard and know something similar? maybe this issue is knowed? or any tips how to investigate it?
